Rumble

Rumble is a member of the Decepticons and one of Soundwave's minions who creates earthquakes by using his hands as giant hammers to smash the ground in order to create

aftershocks on Earth. He also transforms into a purple casette tape along with his companions, Frenzy, Laserbeak, Ravage, Buzzsaw and Ratbat who transform from casette tapes to robot modes. Rumble was percieved as tough and full of firepower, but his fellow Decepticons, being much larger were significantly more powerful. He gave weaker Autobots, such as Hound, Mirage and Bumblebee hard times on the battlefield.
